concare face. The ends of the prongs and 29 are bent to form hea-d elements '50 and 3l, respectively. rl`he head elements of the studs 25, 26 and 27 are-grooved asshown at 32, 53 to provide a central web element 3l for each stud; the Width of each slot or groove 32 and is of the proper size to accommodate the gauge of 'metal employed in the fabrication of the guard plate shown in Fig. 7 and later described.

ln the assembly-and adjustment 'of my razor, the blade 23 is placed upon the cap thestuds 26 andQT: passing through the `holesfn 256 and 3T lof the blade; the lia-t blade is lthus positioned so that-ithe'cntting edges project beyond4 the edges 38, '239 ol" the cap an equal distance.

"ihe guard element'comprises a plate ne;\'t arranged adjacent the: blade and kin combination withfthe cap 2l. In .the.preferred lorm illu strated in Fig.' 7, l:the giiard .plate li .1 is perforated at spaced intervals, bisected by the iinigitudinal:axis S-8,to form key-.hole shaped openings 41,42 and a3; each opening is substantially circular inshape towards the loi-ward end ofthe fguardx-plate Ll() and is slotted rearwardly therefrom. The circular portions ofthe openings ll, e2 and l are suitably spaced'and ofthe proper size to nass the studs 9,5, .26 and 2T, after which and under a limited forward sliding movement of the guard plate, the central webelemenls 3l of the studs enter the. rearwardly disposed slotted portions of their. respective openings. -Referring to -F-iOzalO it will be seen that the composite cap,.bladeandguard plate assembly vis Vsyinmetrical upon either side of the longitudnal'axis which bisects the se feral webxand slot elements of the combination. Thus, due to 4.the co-relation of the gauge'of theguard plate and-width ot the slot openings therein tothe dept-h and width of the; groove and web element-slof the studs, as illustrated, a locking of7 :the guard plate to the cap member occurs to prevent niovementof the guard ,plate either from or towards the cap member. Thus definite lixed gap spacings` are provided at la between the edges 39,39'of fthe cap and the adjacent longitudinal teeth elementslo, el? of the guard plate; the grooves 32 and Si' lying in a plane parallelto that of the'plane of thefcap edges 38, 39,and atfa predetermined spared distance therefrom. -The tiefing or adjustment of the blade edges'' accomplished in 'these gap spacings.

rlhe adjustment and flexing of theiblade is seciired through a wedge-like force acting between the blade and the guard plate of the above assembled combination. A shank member yi8 is pivotedat slt) ytola 'suitable handle 5l); for users who vdo not prefer vthe piif'oted handle of the customary oldfashioned razor, the'cirei'ilar linger receptacle'l will be 'l'ound acceptable. The member #LS is reseafi slotted along its longitudinal axis and .inwardly from its outer end, as at 52 for a j nedetermined distance, to provide side fork members, 5l, .whose combined `width is preferablyless than that of the cap rl`he width of the slot 52 is equivalent to, or slightly in excess of the diameter of the several stud elements of the cap yThe cap, blade and guard being assembled asin Fig. l5, the forks and 5l are entered between theblade and theguard from the rear, as in Figs. ll, l2 and l5, being arranged on opposite sides of the studs 25, El, and 27, which serve as guide elements ltherefor. At the left hand, or forward end oly Fig. 7, will be noted two bosses 55 and 5S, arranged oneoneither side ofthe longitudinal axisol'` the guard, and lia-ving sloping faces, as wedge-like elements inclined from the base of the guard plate. At the rearend oftheguard plate, and bisected-.by the longitudinal axis thereof, is shown a ,third boss 57, having also a sloping face inclined.,from the guard plate as -a'wedge element. AThe angle of inclination of the severalbosses is the same. The length ofthe slot' 52 is such. that as the entering ends :3S and :39 of the respective forks 53, 5l strikethe inclined faces of the forward wedges 56, the base ofthe slot 52 will at the same instant .strike the inclined 'face of the rear wedge 5 7, and guided by the studs 25, Q6 and 217, will under further inward movement, `cause :the ine1nbers 53, 5l, 4S to slide and rise on the, wedge elements 55, 56 and .57, respectively, ,toa contact with the flat bladeglas vin 'Fi-g.l 1l. The forked members 5l by this wedge action move away from the base of the guard plate/40 towards the cap 2l, alwaysfhonv ever, maintaining a condition of parallelism towards such'parts. The edges Gl, 62- constitute fulcrum-elemeiitsand by. this movement'transversely flex the blade2i); through asucccssive range of adjustable positionsl ranging from thatof-zeroYl'lexure shownin Figs. `l-land 16, to that of niaxinnnn lcxu-re asindicated in Figs .1.3, l? and l.

lvhile .thegap ispancings l5 remain constant Ythe transverse passage indicated by the arrow, Fig. 17 is'of variable dimensions, de` pending upon how far. Ithe forked fulcrum elementshave moved away from the base of the guard 'plate vin the adjustment. The Langle A represents the angle included between the planev 63 of the base of the guard plate 40, andA the plane of tangency G4. made bythe spaced cap andguard `in contact with the skin during shaving opera tions. Since vthe gap spacings 4-5 .remain constant under a'll blade flexing conditions, the angle A also remains constant. The cutting edge 23 ofthe blade inFig. 16 crosses the planeet tangcncy 64- while at 'flexed positions intermediate'zero and maximum. liexure it is approaching nearer and nearer Ytienilfiy adjusted on the :tulcruin elements Ul and (52 behind the teeth of the guard, and in the gap spaeings d to suit personal prei:- erences, and to best function with the beard of the user.

The component elements included in the razor, previously described, are preferably fabricated, stamped and embossed from sheet metal, but other materials or die castings may be enipioyed; my invention also applicable to razors of others constructions, such, for instance, as the l -head type, but l deem the balance and swing of the ordinary razor, and as retained in the relstionship of the parts in the preferred 'type illustrated, to be far superior and more in keeping with the several and other advantages indicated in the foregoing description of the preferred parts and their functions. In the stamping of the guard plate 4-0, the longitudinal side edges Vwhich include the teeth elements ab, l5? are formed substantiall;y ii/shaped in section, as disclosed by the drawings.

in the modiiicaton disclosed in Fig. the rear boss 57K of the guard plate made wider than in Fig. liti, or ol" same width as the 'lourth boss T-"g -the bosses 57" and 57" serve as guides for the l'orked members of the shank e8, the width of the slot in said shank beingl oit the proper width 52X, F ig. 2O to function with the side elements of said bosses for such purpose.. lt will be understood that the guard plate d0, Fig. 2l has forward Wedge elen'ients equivalent to the wedge elements 56 and which function with the Wedge eleu'ient 7X in combination with the forked shank inem ber, Fig. for blade Herring purposes in a manner similar to that prevously described with reference to the elements shown in Fig. Yl. ,ln the `iabri ,at'iou oit the bosses iii and 5T", transiuirse slits were made in the guard plate, each slit being bisrazted by the .longitudinal axis oit the guard, and at a prcdeterniined interval apart. To the right of each slit for a distance, as illustrated in Fig. 2l, the metal is depressed, so that the respective slits are widened to enaole the heads and 3l of the studs 28, 29 to pass between, and thereby engage and lock the guard plate to the cap. Inner portions of the head elements 30 and 3l of the studs engage with the adjacent bosses 573', 57x of the guard to resist separation of the cap and guard after such assembly, both prior to, and after the combination therewith of the Ylorked fulcrum elements 53, 54:; and by contact of outer portions of the head elements -(l and 3l against the adjacent base portions of the guard plate as shown in was the Fig. 2l., the cap and guard lock and position each other at spaced gap distances, such as 4:5.

Yln colnliination in a safety rai/.on a, guard plate and a shank member having a forked end; said guard plate having` teeth arranged along its longitudinal eef xs, a pair of wedge-like elements projecting from one face of the plate near the forward end thereof, arranged one on either side of the longitudinal axis of said pla e, and a! third wedge-like element biseeled by said Y ts axis and arranged on the same .face of the plate earthe rearcnd thereof; the forked endof said shank being slidablyv arrangeable on said plate and on either side oit` said third wedge-like portion, and with its opposite end laterally extending beyond the rear end of said guard plate; further inward movement of .said shank member upon said plate, causing the forward and rear portions of the forked men'iber to function with said wedge-like port-ions to raise said shank member from said plate and in parallelism therewith.

88. In a razor, the combination with a detachable blade having opposite longitudinal cutting edges, of a transversely curved rigid cap arranged to support said blade near its cutting edges; a guard plate provided with teeth 4along its opposite longitudinal edges, said plate being detachably locked to said cap at a predetermined distance therefrom and on the opposite side of said blade, with its teeth members arranged at an established spaced distance from the longitudinal edges of said cap; the angle formed between the plane, tangent-to a row of teeth of the guard and the adjacent longitudinal edge of the cap, and the plane of the base remaining constant at all times; and within which established spacing between the cap and guard plate, the said blade is transversel)7 flexible to draw the adjacent cutting edge of the blade nearer and nearer to the lirst mentioned plane of tangeney.

39. In a razor, a blade support transversely concave on its inner face, studs projecting therefrom and along. the longitudinal axis thereof; a guard member having keyhole shaped openings, in its longitudinal axis, for passing head elements of said studs, whence under a limited sliding movement, slotted portions of said openings are engageable with web and groove elements of said studs g, and V-shaped longitudinal edge elements of said guard member locked thereby at a spaced gap distance from the longitudinal edges of the blade support.

l0. In a razor, a blade support tra-nsrerself,Y concave on its inner face, studs projecting therefrom, and bisected by the lon- Igitudinal axis thereof; a guard. plate having openings bisected b v its longitudinal axis, and within which head elements of said studs `are eiigageablc, and V-sha-ped longitudinal edgel elements Aof said guard plate locked therebir at a space-d gap dista nce from the longitudinal edges of the blade support; a flat :flexible blade positioned by said studs intermediate the blade support and the guard plate, with its longitudinal edges bisecting the planes tangent to the teeth of the guard andthe edges of the blade support; a member narrower than the blade support, longitudinall)7 arranged intermediate the blade and the guard plate, and

means for adjustably raising said member away from the guard plate and towards the blade support, and to transversely flex the blade upon longitudinal fulcrum edge elements of said member towards said planes of tain ency.

4l. n a safety razor, a guard member having V-shaped teeth elements arranged along the opposite longitudinal edges; a blade supporting cap shaped to flex a blade transversely; studs rigid with the cap, having web and groove portions engaging slotted openings in said guard plate whereby the longitudinal edges of the cap are set at fixed gap spacings from the teeth elements of the guard member; a blade positioned by said studs between the cap land the guard member with its opposite cutting edges projecting beyond the longitudinal edges of the cap and over the gap spaces; a shank member, forked at one end to provide parallel longitudinally extending fulcrum edge elements and a slot of constant width intermediate said fulcrum elements; said forks slidably engaging on opposite sides of said studs intermediate the blade and the guard member, and with the edges of the cap member overhanging said fulcrum edge elements; and wedge-like elements on the guard plate functioning, under sliding movements of the forked member, to lift said forked member through successive p-arallel positions and create an expansible force inter-mediate the guard member and the blade to fiex the edges of the blade on said fulcrum edges and in said gap spaces behind the teeth of the guard member.

42. In a razor, a blade support transversely concave on its inner face, studs projecting therefrom and along the longitudinal axis thereof; a guard plate having openings bisected by its longitudinal axis and within which head elements on said studs are engageable and V-shaped longitudinal edge elements of said guard plate looked thereby at a spaced gap distance from the longitudinal edges of the blade support; a flat, perforated, flexible blade positioned by said studs intermediate the blade support and the guard plate.

48. In a safety razor, a guard member having teeth elements arranged along the opposite longitudinal edges, a blade supporting cap shaped to flex a blade transversely, means integral with the cap engaging elements integral with the guard member whereby the longitudinal edges of the cap are set at fixed gap spacings from the tee-th elements of the guard member; .a blade positioned between the cap and the guard member with its opposite cutting edges projecting beyond thel longitudinal edges of the cap and over the gap spaces; a shank member forked at one end to provide parallel, longitudinally extending fulcrum edge elements and a slot of constant width intermediate said fulcrum elements; guide elements in the longitudinal axis of' the razor cooperating with said slot, said forks slidably engaging on opposite sides of said guide elements with the fulcrum edge elements arranged, one adjacent each longitudinal edge of the cap and intermediate the blade and the guard member; and wedge-like elements on the guard member functioning, under sliding movements of the forked member, to lift said forked member through successive parallel positions and create an expansible force intermediate the guard member and the bladeI to fiex the edges of the blade on said fulcrum edges and in said gap spaces be hind the teeth of the guard member.

44. In a safety razor, a longitudinally extending shank member having a handle element at one end thereof, the opposite end being inwardly slotted along the longitudinal axis thereof for a desired distance to form forked side elements, the outer edge elements whereof constituting fulcrum elements'.
